Children with avoidant/restrictive food intake disorder and anorexia nervosa in a tertiary care pediatric eating disorder program: A comparative study.

OBJECTIVE: The purpose of this study was to examine the medical and psychological characteristics of children under the age of 13 years with avoidant restrictive food intake disorder (ARFID) and anorexia nervosa (AN) from a Canadian tertiary care pediatric eating disorders program. METHOD: Participants included 106 children assessed between 2013 and 2017 using the Diagnostic and Statistical Manual for Mental Disorders, 5th edition (DSM-5). Data were collected through clinical interviews, psychometric questionnaires, and chart review. Information collected included medical variables (e.g., weight, heart rate, need for inpatient admission, and duration of illness from symptom onset); medical comorbidities (e.g., history of food allergies, infection, and abdominal pain preceding the eating disorder); and psychological variables (e.g., psychiatric comorbidity, self-reported depression and anxiety, and eating disorder related behaviors and cognitions). RESULTS: Children with ARFID had a longer length of illness, while those with AN had lower heart rates and were more likely to be admitted as inpatients. Children with ARFID had a history of abdominal pain and infections preceding their diagnoses and were more likely to be diagnosed with a comorbid anxiety disorder. Children with AN had a higher drive for thinness, lower self-esteem, and scored higher on depression. DISCUSSION: This is the first study to look at DSM-5 diagnosis at assessment and include psychometric and interview data with younger children with AN and ARFID. Understanding the medical and psychological profiles of children with AN and ARFID can result in a more timely and accurate diagnosis of eating disorders in younger children.

Clinical and psychological features of children and adolescents diagnosed with avoidant/restrictive food intake disorder in a pediatric tertiary care eating disorder program: a descriptive study.

BACKGROUND: Avoidant/Restrictive Food Intake Disorder (ARFID) is an eating disorder first described in the Diagnostic and Statistical Manual of Mental Disorders, 5th edition (DSM-5) [American Psychiatric Association, Diagnostic and statistical manual of mental disorders, 2013]. Patients with ARFID do not fear gaining weight or have body image distortions. ARFID involves a persistent disturbance in feeding and eating that results in an inability to meet nutritional and/or energy needs with one of the following: weight loss or failure to achieve appropriate weight gain, nutritional deficiency, dependence on enteral feeding or nutritional supplements and significant interference with psychosocial functioning. To date, studies on patients with ARFID have retrospectively applied the DSM-5 diagnostic criteria for ARFID to reclassify patients diagnosed with DSM-IV eating disorders. METHODS: A descriptive retrospective chart review was completed on patients less than 18-years diagnosed with ARFID after a comprehensive eating disorder assessment between May 2013 and March 2016. The data collected included demographics, anthropometrics, historical information, clinical features, co-morbid diagnoses, need for inpatient hospitalization and psychometric measures. RESULTS: Three hundred and sixty-nine patients were assessed for an eating disorder between May 2013 and March 2016. Of these, 31 (8.4%) received a DSM-5 diagnosis of ARFID. A full chart review was performed on 28 (90.3%) patients. Weight loss or failure to achieve appropriate weight gain was the reason for diagnosis in 96.4% (27/28). All of our patients had 2 or more physical symptoms at the time of diagnosis and 16 (57.1%) had a co-morbid psychiatric disorder. Twenty (71.4%) reported a specific trigger for their eating disturbance. Admission for inpatient hospitalization occurred in 57.1% (16/28) of patients. Thirteen (46.4%) patients had been previously assessed by another specialist for their eating disturbance. None of the patients had elevated scores on commonly used psychometric tests used to assess eating disorders. CONCLUSION: This is the first study to retrospectively determine the incidence of ARFID in children and adolescents using the DSM-5 diagnostic criteria at assessment. The clinical presentation of patients with ARFID is complex with multiple physical symptoms and comorbid psychiatric disorders. Commonly used pediatric eating disorder psychometric measures are not specific for making a diagnosis of ARFID, and may not be sensitive as assessment tools.

School-based peer support groups: a new approach to the prevention of disordered eating.

The goal of the present study was to evaluate the effectiveness of a school-based peer support group designed to improve body esteem and global self-esteem and to reduce negative eating attitudes and behaviors. A total of 214 girls in grades 7 and 8, 115 of whom were in the control group, completed self-report questionnaires immediately before and following the intervention, and three months later. The findings revealed that participation in the 10-session group, facilitated by public health nurses, led to increases in weight-related esteem and decreases in dieting. The role of peer support groups in the prevention of disordered eating is discussed.

Replication of a peer support program designed to prevent disordered eating: is a life skills approach sufficient for all middle school students?

The evaluation of a school-based peer support group previously shown to improve body esteem and global self-esteem and reduce dieting in young adolescent girls was replicated in the present study. A total of 282 girls in grades 7 and 8, 196 of whom were in the control group, completed self-report questionnaires immediately before and after the life skills intervention, and 3 months later. Contrary to the findings reported in the original study, participation in the 10-session peer support group did not lead to improvements in body esteem or eating attitudes and behaviors beyond what was experienced by the control group. Interestingly, participants of the current intervention group exhibited higher disordered eating scores at baseline than those participants in the original study. Implications for matching prevention curriculum with the developmental and symptom levels of students are discussed.
